Using Pico to get state from LED lights is ingenious. Mad props! If you just want to control infrared devices and set their state without first reading their state (like any standard IR remote), looking into BroadLink RM4 Mini. Works with almost everything I've thrown at it.

Do those work with mini split AC units? They have really odd remotes, but they’re IR. We have some Fujitsu halcyon units I would love to control over the web.

It depends - some units broadcast individual commands to turn up/down temp, so those would be easy. Some units broadcast the entire state every time you press the button though (normally remotes with an display on them), so recoding the remote would just give you a state to cycle through. You may be able to find just the individual temperature commands on remotecentral.com or other places online by searching “Pronto Code database” - those can be converted to whatever format you need.

Yes. I have a Mitsubishi mini split and my broadlink (RM3, but effectively the same from an IR standpoint) is able to transmit codes. I did have to train the broadlink unit, which basically consists of putting it into a “learn” mode and then pressing the desired button on the mini split remote.
